I have purchased airbags for my 99 and I need to know how they match with the SRS module. Is there a specific code for this?

The reason I'm asking is because I was going to purchase one from that 'Auction' site, but didn't after seeing the tags on both (the part #'s end with -M1).

Could someone that works for the dealership check the manuals for me?

FWIW, I did order a manual for that year but won't have it for a few days.

Don't want to screw myself out of some cash by being stupid and buying the wrong part.

Thanks.
